Hello everyone,
I have three questions about silica testing for Type II water:

1) NCCLS guidelines state max  silica content at 0.1 mg/L and that silicates 
may interfere with certain assays.  Assay's like IPOX staining and why?  
IPOX staining? 

2) Can water from same source be tested as Type II for microbial content and 
tested as Type III for silica?

3) What do others do about silica levels that are above NCCLS guidelines?

Thanks in advance
